Designing multiband antennas with low volume becomes of practical interest for mobile telecommunications. This paper presents the designs of five small dual band patch antennas for GSM1800 (1710-1880MHz) and Bluetooth (2400-2483.5MHz) applications using a genetic algorithm combined with MoM (Method of Moments). A substrate with dielectric constant 3.2 and height 8mm is used for the first two dual band designs. The height is reduced thanks to the optimization process to 6mm in the third design by inserting a shorting pin to the fragmented patch antenna. The height is further reduced to 4mm in the by inserting two shorting pins. In the final design with three shorting pins, the height is only 3mm. The patch dimensions are similar to that of the conventional rectangular patch for the center frequency of the lowest frequency band but with the advantage of having dual-band operation at the desired bands. Genetic algorithm optimization is used to optimize the patch geometry, feed position and shorting positions. HFSS is used to carry out simulations. The antenna thickness is reduced from 8mm to 3mm by incorporating shorting pins which position is optimized by the genetic algorithm. Design of Dual Band Patch Antennas 27

“…Many filtering antennas, in different topologies, have been designed using filter synthesis approach, in which the antenna acts as the last resonator in the filter. Filtering antennas have been implemented in different forms including rectangular patch [1], circular patch [2], patch array [3], Γ-shaped antenna [4], slot dipole [5], monopole antenna [6], inverted-L antenna [7], Yagi antenna [8], waveguide slot antenna [9], and dielectric resonator antennas [10].…”

Abstract-Design, simulation, and measurement of a compact filtering microstrip antenna is presented. A feed line, two hairpin resonators, and a rectangular patch are integrated to form the filtering antenna. The elements together function as a third order bandpass filter with Chebyshev equal ripple response of 0.043 dB at midband frequency of 2.0 GHz. The rectangular patch acts not only as a radiating element, but also as the last resonator of the bandpass filter. The proposed filtering antenna exhibits good out-ofband gain suppression, flat in-band gain response, good selectivity at the band edges, and well-shaped radiation pattern.

“…The filtering antennas were also achieved by different forms, such as circular patch antennas [7], slot dipole antennas [8] and monopole antennas [9,10]. In [9], a Γ-shaped monopole antenna is proposed, which achieves the purpose of the high band-edge selectivity, but the coupled line resonator is needed.…”

Abstract-This paper presents a simple microstrip filtering-antenna with compact size for WLAN application. The T-shape resonator through an inset coupling structure can be treated as the admittance inverter and the equivalent circuit of the filtering-antenna is exactly the same as the bandpass filter prototype. With a little extra circuit area, the proposed filtering-antenna has almost twice wider bandwidth, good skirt selectivity and high suppression in the stopband compared to the conventional microstrip antenna.
